ALBANY, N.Y. (CBSNewYork/AP) — Gov. Andrew Cuomo says he has serious concerns over a bill that would legalize medical marijuana in New York just hours before the midnight deadline.

The Democrat stymied the efforts of supporters of the so-called Compassionate Care Act Monday, saying that the measure should ban smoking the drug, cut down the number of illnesses it can be prescribed for and require that the program be evaluated in five years.

“If we can address the concerns, there will be a bill,” Cuomo told public radio’s “Capitol Pressroom” while defending his suggestions. “But I’m not going to be part of a system that is just going to wreak havoc.”

State Sen. Diane Savino, the Staten Island Democrat who sponsored the measure, said the bill already addresses many of Cuomo’s concerns.

“We have certainly way more support than we need in the Senate to pass the bill,” she said.

Under the Compassionate Care act, smoking would be banned for anyone under the age of 21, although the drug could still be consumed through a vaporizer, edible or oil. The bill would also allow patients with one of 20 diseases to be administered marijuana under the supervision of a health care professional. Cuomo wants the legislation changed so only doctors could prescribe the drug.

Savino called Cuomo’s position on smoking marijuana a “nonstarter” and disingenuous, citing his executive order to allow 20 hospitals statewide to administer the drug.

“It’s a little distressing that they came in at the 11th hour with a list of concerns and demands,” Savino said. “Many of them are already in the bill.”

Gabriel Sayegh, of the state Drug Policy Alliance, also lashed out at the governor’s requested changes, first reported in the New York Daily News.

“It’s disappointing to have the news of these concerns come out at the very last minute in a leaked Daily News article,” Sayegh told The Associated Press. “It’s hard to imagine the governor’s serious about getting this done.”
